^MWANZA STD TREATMENT TRIAL^

A cluster randomised trial was carried out in Mwanza Region, Tanzania to
measure the impact of improved STD treatment services on HIV incidence in 
the general population. Twelve communities were matched into six pairs and 
one community in each pair was randomly selected to receive the intervention. 
A cohort of around 1000 adults aged 15-54 were randomly sampled from the 
general population in each community and followed up for two years to record 
the incidence of HIV infection. The dataset includes data for the 8549 cohort
members with HIV test results at both baseline and follow-up and who were 
HIV-negative at baseline.
